T 0 all whom it may concern:

Be it known that I, CORYDON E. Rosnns,

a citizen of the United States, residing at Seattle, in the county of King and State of W ashington, have invented certain new and useful Improvements in Means for Producing and'Utilizing Rays of Light for Therapeutic Purposes, of which the following is a specification.

- This application is filed as a continuation of, and substitute for, my concurrently pending application filed February 16th, 1903, Serial Number 143,642 in which there is shown and described a high candle power incandescent lamp, form of filament, inclosing hood, reflecting surfaces therefor and corrugated refiector of the same form and arrange ment set forth and summed up in the claims to which this application is confined, for producing and utilizing rays of light ,for therapeutic purposes.

, Sunlight is-so rich in ultra violet rays that, before it can be directed for a sullicient length of time upon any malignant or deepseated disease ossibly destroying their germs, it inevitably produceQ erythemia, a diffused inflammation, commonly designated as sunburn, painfully and seriously aggravating and not infrequently more dangerous than the disease itself, and, therefore, the impossibility of utilizing the combined rays of the sun, for the destruction of the germs of skin disease, and particularly of malignant diseases of any kind, has long been recognized.

Light from clusters of commonly used incandescent and other lamps, although a good substitute for hot water bags, bricks, etc, for relieving pain and producing pcrspiration, has never been successfully used to destroy any chronic disease of theskin and much less the germs of any malignant dis ease because of the insufficient intensity of the rays due to low candle power.

When Finsen found the germs of lupus, (tuberculosis of the skin) were destroyedby isolated violet rays of light directed and con-- centrated by passing them through a crystal ressed against the diseased tissues thereof, is was the to discover that light rontained so much as a single ray capable of tie etroying the germs of even one of. the most superficial of numerous malignant diseases, and the first to discover any means by which it 1s possible to successfull utilize any ray of light for the destruction. 0 malignant disease 55.

of any kind or character, although sunlight had long before been known to contain all rays of light and heat necessary for sustaining and maintaining both health and hfe in human beings.

Violet rays of light have so little penetrative force that they are not destruetitze er the germs of lupus until concentrated and d1- rcctly' conducted to contact with the'germs of lupus by a crystal firmly pressed thereon, 65.

and while on the other nand the X-rays subsequently discovered by Roentgen pass ontirely through the body, and to a limited degreethrough the deep-seated bones thereof in the absence of any medium, and are destructive of lupus, and furthermore, retard the growth of germs of epithelioma, themost superficial of a large variety of incipient cancers when of small area, and which the violet rays will not, the X-rays will not entirely destroy cancer germs at any stage of that disease. The use of the X-rays, however, 1s in: frequently resorted. to as a remedy for the germs 'of any skin diseases because frequently liable for causes unknown to set u an inso curable progressive breaking down of healthy Issues, which starting at the finger tips has been known to eventually destroy the arm and finally the li e of the sufferer, notwithstanding repeated skilful surgical operations in effort to retard its progress, and in other cases to produce less progressive incurable ulcerations.

My discovery, demonstrated by long and frequent practice upon a great variety of diseases and particularly malignant diseases, is that a plurality of differing rays when como red in a high candle power light, poor in -violet rays, will destroy the germs of malignant and other diseases with greater rapidity than will any isolated ray, and in the absence of any injury to healthy tissues; that as the number of difieringrays combined are 1ncreascd in a high candle power light, poor in ultra violet rays, the range of destruction of 10o light is extended. to the germs of deep seated lmalignant and also other diseases not de- 'lating. the 'absorbents lamp, necessar y consists in certain features combined in a light of the highest candle power poor in ultra violet rays, even when to a degree entirely destroying both the diseased and surrounding healthy tissues. Furthermore, that when an incandescent electric lamp of high power is combinedandarranged within ahooded structure hereinafter described and claimed the rays of light project therefrom upon the diseased tissues of the human body, both the superficial and deep seated germs thereof are destroyed, in larger numbers and variety than heretofore, by simultaneously stimulating the capil- 'laries, the hemoglobin of the blood to quickly give off and take 11 oxygen destroying the toxic matter of the b ood, even to syphilis, and rapidly increasing the red blood corpuscles to a degree promoting tissue metabolism, stimumatter, producing counter-irritant effects, diverting the blood from the deep seated vessels, an analgetic eflect through rapidly vibrating nerve center's, produce an anesthetic effect due to combined action of these several effects.

' The object of my invention is therefore the production of means by which all of the rays of a high candle power light, poorin violet rays, may be projectedwithin predetermined limits upon the diseased tissues of the human body, in a form appearing thereon'as lines of eater illumination, with one or more briliant spots thereinof suflicient intensity to produce cauterization of small area of diseased tissues, when the source of light is held in close proximity thereto, and thereby destroy'the germs of malignant diseasesiin va- ,rieties limited only by the sum of all the rays oflight, poor in ultra violet rays, and without setting up inflammation.

More specifically stated the object of my invention is to utilize the rays of light, from a high candle ower incandescent electric poor in ultra violet rays, by inclosing such lamp within a hooded structure provided with reflecting surfaces of such form and arrangement, that the rays of light projected therefrom may be confined within predetermined limits, and have the appearance, when directed-upon the human body or other surface, of lines of greater illumination out of arallel with each other and one or more bri iant spots within said area of sufficient intensity to produce cauterization of diseased tissues when the lamp is held in close proximity to but not in contact therewitl With these ends in view, my invention of novelty in the construction, combination and arrangement of parts, by which the said objects and certain other objects heremafterappearing are to remove extraneous lamp for therapeutic purposes, with the lamp shown in full lines,

embodying my'invention and illustrating the latest details tending to perfect its construction; and, Fig. 2, a diagrammatic illustration ofpthe form and arrangement of the rays projected by the lamp upon the human body.

Similar letters and numerals of reference indicate the same parts in the different views of the drawings.

A indicates an incandescent electric lamp, which for superficial malignant. diseases may be from 100 to 300 candle power but for either superficial or deep seated malignant diseases, should be from 300 to 500 candle poWerand upwards. The lamp A is inclosed by a hooded structure B consisting of a cone 1 below which the lamp A partly projects into a cylindrical casing 2, secured to the base of the cone and provided at one side with a handle 3 for manipulating the lamp from a swinging position, and with an opening 4 to enable the operator to inspect and determine during the courseof the, treatment of the patient, the desired extent, character and intensity thereof, which for convenience is designated a director because it gives direction to the rays upon the patient. The lamp A isdesigned to represent either a 300 or 500 candle power or upwards, and is of the ordinary construction of high power. lamps upon the market.

At a and the bulb end of the lamp is a reflector .5 annular in form and substantially filling the space between the lamp and cone 1 as shown, which reflector may extend at a right angle to a vertical line through the lamp, but as sh and should be so with the cone reflecting surface to ren er the rays of greater brilllancy than they'would otherwise have. The reflector 5 is preferown is preferably inclined,

- ably provided with a number of circular corrugations 6 curved in cross-section and equal distances apart, and for the best effects not less than five in number, although it would be no substantial departure from my invention to have these corrugations angular in cross-section and of less number, notwithstanding that long and frequent experiments demonstrate that a less number do not propoint between the neck extremity constructed as to coo eratej the sides ofthe I duce quite so good therapeutic eflects as the number shown.

The form of the reflecting surfaces of the hoodas a whole and the relative arrangement of the lamp thereto are such that the light projected from the'hood against an o posing surface appears to the eye to be in tlie form of a number of lines out of parallel with p more bri see, res

some of the lines crossing each otherand at their 1point of crossing forming one or liant spots which, in therapeutic effect as compared with the lines uncrossed, are Concentrations of light and heat desirable and necessary in certain cases, not only for quickly relieving a patient for the time being by vigorously exposing a small area of diseased tissue thereto, but for quickly destroying by cauterization certain diseases, such, for example, as lupus (tuberculosis of the skin), and also epithelioma, (skin cancer), particularly when the germs thereof are in such parts in small area or areas that a seemingly heroic treatment is required in order to prevent, as quickly as possible, their spreading or escaping destruction due to the lesser intensity produced by the heat and light from the separate lines. In other Words, the further concentration of light and heat produced by the crossing of the linesis not only desirable to, in certain cases, quickly relieve a patient either for the time being or for subsequent purposes, but necessary for vigorously treating small areas of diseased tissues, and for quickly destroying by cauterization, certain diseases, such for example, as lupus (tuberculosis of the skin) and also epithelioma (skin cancer) particularly when the germs thereof are in such numbers in asmall area or areas, as to require this seemingly heroic treatment in order to prevent their spreading, or possibly escaping destruction if subjected to rays of less intensity.

The lamp A may be suspended in the hood as shown, and electrically connected with a suitable source of electric supply by any desired ordinary means adapted for the purpose, for so far as my invention is concerned, and as previously disclosed herein, it is immaterial as to just what means of suspension and electrical connection are employed, so long as the lamp is held within the hood in substantially the osition indicated in the drawing and is furnished with an electric hurrent sufficient for the purposes described.

The best means so far devised, and which are approved by the board of underwriters for suspending and electrically connecting the lamp, consists in providing the upper end of the cone with an annular flange 7 and inclosing the sheet-metal cone with a sto perlike piece of porcelain 8, the lip of whic opposes the underside of the annular flange/*7. The underside of the porcelain stopper 8 is recessed, that is held out to receive and thereby prevent lateral movement of a porcelain disk 9, between which and the stopper 8 is a sheet oi'asbestos 10 for insulating purposes. Passing through both this porcelain stopper and dish and the layer of asbestos, are bolts 11 preferably four in number, equal distances apart adjacent the upperside of the stopper 8 with washers l2, and ad'acent the lower side ofv the dish 9 with was ere ill--33, two

of which bolts 11, as indicated in the drawing, are provided at opposite ends with thumb-nuts 14, which, together with the washers, serve to clamp on the inside of the disk 9, the insulated Wires 1515 of the lamp, and electrically connect said wires with wires 16- 16 leading to the source of electric al supply for the lamp.

Embracing the contract-ed portion of the neck of the lamp A are spring tongues 17 sufficient in number and distributed so as to embrace and hold. and sustain the weight of the lamp when surrounded by a circular coiledspring 18, the upper end of these tongues being bent to form what has before been designated as and may be washers 1-3 -13.

The stop er 8 is designed to be fitted tightly within and against the upper end of the cone and to thereby form in connection with the reflector 5, a dead air chamber for the urposes of preventing the burning of the insu ation of the wires of the lamp and also to reduce as far as may be heating the upper part of the cone, when the lamp is in use.

Surmountin'g the flange 7 of the cone is an inverted cup-shaped piece of porcelain 19 secured to the flange 7 by boltsfnot shown,

and having a bushing 20, to which is screwed a four-way tubing 21 in the upper end of which, by a screw-plug 22, is secured a ring 23 by which to hang the lamp by means of a cable enabling it to be swung. into the varied desired positions when in use, the horizontal arms of the four-way tube being also provided with insulating bushings 24, through which the wires are respectively projected for the purposes of their connection to a cable or line wire leading to a source of supply.

The cup 19 provides a chamber connectin with the four-way passage in the tubing, an

a means for forming a dead air space of sufficient degree preventing the heat from burning the wires 16-16 and particularly. their insulating covers.

The bolts 11 may be and are prevented from burning by means of nuts 25, square or of irregular form, depressed in recesses formed in the stopper 8 and the wires 1313 are prevented from crossing or short-circuiting by reason of any turning of the lamp or the hood and against the possibility of any such occurrence, by means of a porcelain block 26 projecting down between the wires 13 and preferably suspended in this position by a screw-bolt 27 passing through t per 8 and disk 9 with its lower end secured to the block and tightened by a nut 28 countersunk in the upper face of the stopper.

"While these details of devices and their arrangement for-suspending the lamp within the hood and for preven irg the wires and llu e stoptheir insulations from being charred or de- I about the lam tance above the patient and state that I am the apex of said hood, a reflector arranged in the claimed herein, for my invention will be none the less present in a structure not showing these details, when any other common and well-known means are employed to sustain the lamp, the hood and the reflector in their operative positions as shown, nor if the dead air space between the reflector and the stop per is omitted, and the upper portion of the cone is open by perforationsor otherwise] For operation, these lamps are usually sus-, ended by an overhead cable and counteralanced by a weight, so as to be convenof manipulation over the patient, pref- Y erably in a lyingient I position, stripped of eing held some disdown clothing, the lamp first gradually brought nearer to him as the treatment proceeds and which may be done without inconl venience, owin to the anesthetic effect of the heat, while in the meantime the operator regulates the heat as desired or necessary, and which .he is enabled to do by looking through the pee -hole 4.

The peep-ho e is particularly necessary when the hood is brought down very low and particularly for the purpose of cauterizing when it is necessary for the o erator to be able to lower the lamp so as to ring the concentrating points produced by the crossing of the beamsdirectly upon the spot to be cauterized, and to watch its progress so as to determine when to cease cauterization.

In conclusion it is roper at this point to rst to employ for any purposes, and particularly for therapeutic purposes an incandescent light of great heat and light-giving power securedin a hood flexibly sus ended and provided with refleeting sur aces, one of which is arranged about the neck of the lamp and forming with the others a continuousnreflecting surface adapted to project the heat and light rays from the hood and confine said projected rays within a redetermined area.
